Limit editing to technical corrections
You can moderately correct:
- exposure;
- white balance;
- rotation;
- cropping;
- light contrast adjustments;
- sharpening within natural limits.
Avoid edits that remove:
- scratches;
- selective dirt where removal would hide marks;
- dents;
- corrosion;
- discolouration;
- parts present in the original image.
Editing should make the photograph easier to read, not change what the buyer will receive.
